GIN-SAW.

SPECIFICATION forming part o f Letters Patent No. 287,450, dated October 30, 1883.

Application filed July 9, 1883.

To all whom it may concern/.-

Be it known thatY I, CHARLES W. MANN, a citizen of the United States, residing at San Marcos, in the county of Hays and State of Texas, have invented a new and useful Gin- Saw, of which the following is a specification, reference being had to the accompanying drawings.

' This invention relates to gin-saws; and its object is to provide means for enabling the ready and convenient detachment of the'teeth for substitution or other purposes, whereby superior advantages in point of simplicity, inexpensiveness, durability, and general efficiency are secured.

In the drawings, Figure lis a side elevation of a gin-saw embodying my improvements. Fig. 2 is a side view, in detail, of a section of the periphery of the saw. Fig. 3 isI a longitudinal sectional view of the section shown in detail, Fig. 2. Fig. 4 is a transverse sectional view of the detail section shown in Fig 2. Fig 5 is a perspective detail view .of

one of the teeth.

Referring to the drawings, A designates the blade of the saw, which consists of a plate or disk having a regular periphery, B, that 'is preferably beveled to the edge, as shown. On the periphery of the disk A are secured a number of segmental plates or sections, C, forming a continuous series, these sections being bifurcated, as at D, on their inner edges, so that the edge of the disk will be received into the bifurcations, and be embraced by the sides E E of the bifurcated portions of the sections, while rivets F, or other suitable fastening devices, are passed through the sides E E" and through the disk A, to securely retain the sections on the edge of the disk. The teeth G are cast in the solid portions H of the sections C, that project from the periphery of the disk, and they proj ect from the edges of these solid portions. The teeth G consist of perfectly-straight portions I, that are preferably roughened, for purposes that will be presently described, and pointed portions J, that are bent at an angle to the main portions I, and have straight under edges, K. The sections C can be formed of cast-iron, and the teeth, which are preferably formed of steel, are cast in the solid portion H up to the bend, when these straight portions I of the teeth will all (No model.)

The advantages of my invention will bereadily understood and appreciated. In my invention the fine steel teeth will wear much longer, and are not liable to become bent or displaced. The smooth, round, thorn -like shape of the projecting portions of the teeth will give a better staple, and be especially effif cient; and there is a well-defined space between each tooth, and the length of these teeth will effect less chipping ofthe lint.

My invention also admits of easy substitution in case the teeth became worn or broken by stone or other hard substances, so that the periphery of the saw will always be complete and up to its full capacity.

It will also be understood that the saws at present in use. can be readily equipped with my improvements by simply striking off their teeth and turning up the blades, ready for the reception of the herein-described toothed sections. e

If necessary, the gin-ribs to be used in connection with my improved saw canbe provided with a crease or.' depression in each side tol provide for the passage of the sections C.

I claim as my inventionl. As an improvement in gin-saws, the coinbinationV of the disk or blade, the segmental plates having the solid edge portions, and secured to the periphery of the disk, andthe series of teeth having straight Shanks that are inclosed in the said solid edge portions, and pointed, thorn-like projecting portions bent at an angle to theshanks, the teeth being secured in a continuous row on each segmental section, with all the shanks radiating from the center of the blade and all the points at a corresponding angle to the periph ery of said blade, substantially as and for the purpose set forth.
